Actually any ORBX created in Daz3D has this issue.
I've uploaded a simple test scene https://drive.google.com/file/d/1ao8huM-uPDZCvy_lJHXZcLfk-GuDBzkG/view?usp=sharing The scene contains just two primitive plane objects.

In Unity:
1. Octane -> Settings -> Load Octane
2. Octane -> Load ORBX, select ...

Did somebody tried to export a scene from Daz3D in ORBX format and import to Unity? The reason I try to do it Daz plugin cannot render stereo 360 for now. Unity plugin does it perfect.
So, when I try to load ORBX in Unity I get the error "Invalid AABB a".
Any idea?

Hi MaxXR,

Try to change the directional Light to "Baked". Also try to uncheck AI Denoiser in PBR Lightmap.

I've tried to use the script to assign the lightmaps in runtime mode but it doesn't work form. Actually my script is a little bit more complicated:

void Start () {

string m_Scene = SceneManager.GetActiveScene().name;
string m_pathLigtmap = "Assets/" + m_Scene + "/Octane/";

DirectoryInfo m ...

How to bake the lightmaps? I can successfully render in PBR Viewport but "PBR Lightmapping" creates black PBRLightmap_N_LIGHT_DIRECTION.png and PBRLightmap_N_IRRADIANCE.exr files.
What am I missing ? Any special settings for camera etc?

My bad, I forgot to set my light as static.
